The Dragon UA have a single reference to Fizban...but Fizban is an avatar of the cosmic overgod of all Metallic Dragons in the Multiverse, not just Dragonlance. It also references a Greyhawk deity and two Forgotten Rralms Dragons, and has Gem Dragon and Koblod material (neither of which exist in Krynn), so the UA is not Drsgonlance specific.
I'm still keeping my eyes open for a Fizban Planeswalker.
